4 Sheets-Sheet 2 Patented May 2, 1972 4 SheetsSheet 4 OUTRIGGER FORMOORING A WATER VEHICLE This invention relates to an outrigger formooring water vehicles. Previously known structures, e.g. thoseaccording to the Swedish patent 307,905, have been subject to certainweaknesses which have come into evidence in practical use. It has thusbeen proved that the connection to a quay or bridge at rough inshore seahas been exposed to very great strains and in some cases broken. Thetransports have turned out unnecessarily costly and cumbersome by thebulky design of the outriggers. It has further been desired to be ableto dismount the outriggers in a simple manner, i.e. in view of iceconditlOl'lS.

By an outrigger according to this invention there is provided a strongand simple structure, a substantially simplified dismounting or e.g.winterkeeping and the outrigger will further become very simple to stowaway or store in a spacesaving manner, and thus transport costs will bedecreased considerably. These advantages are achieved by constructing anoutrigger consisting of a device being pivotable or'turnable in avertical plane and connected to a quay, bridge or the like, and a boomdetachably secured to said device and possibly also to the quay.

A description of an embodiment of the invention selected by way ofexample will follow below with reference to the accompanying drawings.

FIG. 1 shows a plan view of the outrigger and FIG. 2 a partly sectionalelevation along a line 11-11 of the outrigger with the device raisedinto its dismounting position,

FIG. 3 shows a sectional view of the boom along the line Ill-III andFIG. 4 a sectional view along the line IV-IV of the boom, FIG. 5 shows aplan view of an embodiment of the attachment to the quay of the boom andFIG. 6 shows a sectional elevation along the line VI-VI of theembodiment according to FIG. 5,

FIG. 7 shows a plan view of a further embodiment of the attachment tothe quay of the boom,

FIG. 8 shows a sectional elevation along the line VIII-VIII of theembodiment according to FIG. 7, and

FIG. 9 shows a plan view of a way of disposing a plurality of booms in adevice.

A boom 2, which in principle may consist of any elongated structure, issupported at its end directed outwardly of the quay in a known manner,e.g. by means of a floating block 5. The end of the boom directed towardthe quay is supported by means of a dismountable hinge or a keep 7 ofeither the quay or a portion of a device which is designed generallyby 1. The device 1, which is hingedly secured to the quay at at leasttwo points, retains the boom 2 by means of guides 3 and/or bolts 4 in adesired angular position with respect to the quay. The

. guides 3 may consist of a substantially U-formed structure shown inFig. 3 and which partially encloses the boom 2, but it is understoodthat they may be formed in another manner. The guides 3 may, as shown inFIG. I, extend in the longitudinal direction of the boom from a pointrelatively near to the quay and unto the portion of the device remotefrom the quay or, as shown in FIG. 9, extend for only a smalllongitudinal portion of the boom 1. The boom 2 may, although it is notnecessary, by means of one or several bolts 4 be detachably secured tothe device 1. When dismounting the boom 2 the bolt 4 is removed (if theoutrigger is provided with such bolts), the device I will be pivoted orfolded upwardly-inwardly to the quay, which is indicated in FIG. 2 bymeans of a dashed double arrow, and the hinge or keep 7 of the boom 2 islifted out of its position. On mounting the procedure is reversed, thedevice 1 being lowered down onto the boom 2.

Another embodiment of the attachment to the quay of the boom 2 is shownin FIG. 7 and 8. This embodiment makes a reinforcement of the outriggeraccording to FIG. 1 subsequently to its mounting to the quay, which maybe necessary if the charges on the outrigger have proved greater thanwhat was estimated initially. The hinge 7' will then be mounted, e.g. bywelding, to the existent keep 7 and secured to the quay. On

dismounting the tube bolt 8 is withdrawn out of the hinge 7 and thedevice 1 is swung up-as shown in FIG. 2.

In FIG. 7 also two stays 9 are shown, which are welded diagonallybetween the tubes of the boom 2. These stays 9 reinforce the portion ofthe boom 2 which will be exposed to the greatest charges.

The device 1 may also be formed to retain a plurality of booms 2 in adesired position with respect to the quay, which is shown in FIG. 9.Thus the number of attachments to the quay may be diminished, but by wayof compensation the device 1 is to be made more robust as if it weredesigned for one boom only.

The device 1 may if it is designed for a plurality of booms 2,preferably be in the form of a triangle, which does not, however,exclude other forms. The inner angles of the device 1 may be providedwith reinforcements 6, e.g. plates, tubes or beams.

It is understood that the invention will not be limited to theembodiments described above but may be modified within the limitsdefined by the claims.

WHAT IS CLAIMED IS:

1. An outrigger for mooring water vehicles to a shore supported member,comprising:

a support device pivotally connected to the shore supported member attwo points, said device having two rigid support members extending fromsaid pivoted connections,

guide means joining said support members at the end distal from saidpivoted connections, and

a cross member extending between said support members at a positionbetween said guide means and said pivotal connections; and

a boom pivotally and detachably connected to said cross member andretained by said guide means in a predetermined angular position in ahorizontal plane with respect to the shore supported member,

whereby pivoting of said support device disengages said guide means fromsaid boom and causes the end of said boom pivotably and detachablyconnected to said cross member to be brought over the shore supportedmember, thus allowing said boom to be easily detached from said supportdevice and stored ashore when desired.

2. An outrigger for mooring water vehicles to a shore supported memberin rough seas, comprising:

a rigid support device;

a first pivotal connection means for connecting said support device withthe shore supported member such that said support device is pivotable ina vertical plane perpendicular to the shore supported member;

a boom having a floater at one end and connected to said support deviceat the other end by a second pivotal connection means connected to saidboom and detachably connected to said support device; and

a U-shaped guide member attached to said support device for retainingsaid boom in a desired angular position in a horizontal plane withrespect to the shore supported member,

whereby pivoting of said support device disengages said guide memberfrom said boom and causes the end of said boom detachably and pivotallyconnected to said support device to be brought over the shore supportedmember, thus allowing said boom to be easily detached from said supportdevice and stored ashore when desired.

3. An outrigger according to claim 2 wherein said U-shaped guide memberextends in the longitudinal direction of said boom from a pointrelatively near to the shore supported member to the portion of saidsupport device distal from said shore supported member.
